 " sous les tropiques, les choses se passent sans doute autre- 

 ment. On trouve deja I'indice de ce fait dans le midi de 

 I'Europe chez les Empusa, qui hivernent a I'etat de larve 

 et se transforment au printemps suivant." 



A Mantis sp., which I had had in confinement in my 

 house at Calcutta for about a week, laid, during the night 

 of July 16th — 17th, an egg-capsule, from which I found 

 the young emerging early on the morning of August the 

 4th. A Schizocephala bicornis, captured about the same 

 time as the Mantis, and confined in the other compart- 

 ment of the vivarium, deposited an incomplete egg-mass 

 on the very same night, but the young did not quit the 

 eggs till August 16th.
